And remember that there are several different commercial detection 
strategies--some of which work better in different areas.  Therefore, I 
recommend trying out some of the others.  Also, you should probably 
disable the aggressive setting while testing.

Besides the default strategy (blank frame), there's scene change, logo, 
blank frame and scene change, and all.  And, note that you must have 
"Automatically Flag Commercials" enabled to use anything other than 
blank frame.
